doc: Initial doxygen framework for NSH SFC project

A first attempt for a documentation generation using Doxygen for
the NSH SFC project.

Doxygen tagging and documentation in the code still need to be done.

Based on a copy of the Doxygen framework in VPP. Top Makefile added
to (only) build documentation.
